Abelian ChernSimons vortices and holomorphic Burgers hierarchy
Pashaev, Oktay; Gürkan, Zeynep Nilhan (Springer, 200707)We consider the Abelian ChernSimons gauge field theory in 2+1 dimensions and its relation to the holomorphic Burgers hierarchy. We show that the relation between the complex potential and the complex gauge field as in ... 
The AblowitzLadik lattice system by means of the extended (G′ / G)expansion method
Aslan, İsmail (Elsevier, 201007)We analyzed the AblowitzLadik lattice system by using the extended (G′ / G)expansion method. Further discrete soliton and periodic wave solutions with more arbitrary parameters are obtained. We observed that some previously ... 
Absolute cosupplement and absolute cococlosed modules
Keskin Tütüncü, Derya; Toksoy, Sultan Eylem (Hacettepe Üniversitesi, 2013)A module M is called an absolute cococlosed (absolute cosupplement) module if whenever M ≅ T/X the submodule X of T is a coclosed (supplement) submodule of T. Rings for which all modules are absolute cococlosed (absolute ... 
Absolutely spure modules and neatflat modules
Büyükaşık, Engin; Durğun, Yılmaz (Taylor & Francis, 201502)Let R be a ring with an identity element. We prove that R is right Kasch if and only if injective hull of every simple right Rmodules is neatflat if and only if every absolutely pure right Rmodule is neatflat. A ... 
An analytic approach to a class of fractional differentialdifference equations of rational type via symbolic computation
Aslan, İsmail (Wiley, 201501)Fractional derivatives are powerful tools in solving the problems of science and engineering. In this paper, an analytical algorithm for solving fractional differentialdifference equations in the sense of Jumarie's modified ... 
Analytic investigation of a reactionDiffusion brusselator model with the timespace fractional derivative
Aslan, İsmail (De Gruyter, 201404)It is well known that many models in nonlinear science are described by fractional differential equations in which an unknown function appears under the operation of a derivative of fractional order. In this study, we ... 
Analytic investigation of the (2 + 1)dimensional Schwarzian Korteweg–de Vries equation for traveling wave solutions
Aslan, İsmail (Elsevier BV., 20110215)By means of the two distinct methods, the Expfunction method and the extended (G0/G)expansion method, we successfully performed an analytic study on the (2 + 1)dimensional Schwarzian Korteweg–de Vries equation. We ... 
Analytic solutions to nonlinear differentialdifference equations by means of the extended (G′/G)expansion method
Aslan, İsmail (IOP Publishing, 201010)In this paper, a discrete extension of the (G′/G)expansion method is applied to a relativistic Toda lattice system and a discrete nonlinear Schrödinger equation in order to obtain discrete traveling wave solutions. Closed ... 
Analytic study on two nonlinear evolution equations by using the (G′/G)expansion method
Aslan, İsmail; Öziş, Turgut (Elsevier, 200903)The validity and reliability of the socalled (G′/G)expansion method is tested by applying it to two nonlinear evolutionary equations. Solutions in more general forms are obtained. When the parameters are taken as special ...
